ANTIFR-IOTION JOURNAL BOX.

APPLIOATION FILED JUNE 21.1904.

2 SHEETS-SHEET Z 5016157286868: fnvenfai" Delos .fllien hold the inner and outer bearing members l and a sleeve detachably mounted thereon,

firmly against end. thrust and endwise longitudinal displacement.

At the respective ends of sleeve 3 are provided collars 3, provided with annular flanges or tracks 18, upon which roll reduced portions or necks 17 of the respective rollers 7, and annular grooves 23 to receive the heads or flanges 27 at the ends of said rollers. These collars are attached to and supported by caps 14:, which are interiorly screwthreaded to engage over corresponding screw-threaded ends of the hub or outer shell 1.,the collars being secured. to the respective caps 14 by screws passing through holes in said caps and screwing into said collars. The caps 14 have central openings which lit over the corresponding portions of the central shaft or journal 2, and thereby center the collars 8 and the series of separating-rollers 7. Rings 20 are provided at the ends of these rollers, said rings surrounding the entire series of rollers and engaging with the reduced portions 17 thereof to hold thesame in rolling contact with the flanged por-.

tions 18 of the collars 8.

At each end of the box I prefer to provide dust-proof end bearings, which may consist of gaskets or washers 26, of fiber or other suitable material, supported by end caps 15, which are recessed to contain said washers. Each of the caps 14 may be recessed to receive a dust-proof packing or felt washer 30, against which the end bearing-washer l6 bears. The central axle-shaft or journal 2 may have a collar or flange 12 and a screw portion 32, receiving a nut 33, the box as a whole being held between'the said flange 12 and nut 33, the outer face of one end cap 15 bearing against the flange l2 and the outer face of the other end cap 15 bearing against the nut 34 designates a jam-nut for the nut 33..

It is desirable to prevent rotation of the inner end ca 15, and to this end it may be provided wit a notch-35, engaging with a projection, as a pin 36, on the axle member When the journal-box is in use, the cylinder members 11 engage with the flange or ribs 16 of the antifrietion-rollem, which in turn engage with the groove 13 in the sleeve 3 to hold the members 1 and 3 against relative endwise displacement. Hardened-steel Washers 38 may be provided at the inner ends of cylinder members 11 to take the wear and end thrust.

It will be seen that when the nuts 34l and 33 are unscrewed and the cap 14 at the outer end of the journal (shown in Fig. 1) is' removed it will only-be necessary to loosen screws 21 in order to remove the innercyli-nders 11, rollers 6 and 7, and sleeve 3*when it is desired to clean or oil these parts.

That I claimis? 1. The combination of a central journal means for preventing relative rotation of said sleeve and journal, a collar at each end of the sleeve and engaging the sleeve, an outer bearing member comprising a cylindrical shell, and two inner cylinders detachably secured to the shell and separated to form an annular channel, washers at the inner ends of said inner cylinders, a series of antifriction-rollers around said sleeve, each having an annular rib to engage in said channel, said sleeve being provided with an annular roove to receive and engage said annular ri s to prevent longitudinal movement of the sleeve and rollers and outer bearing member, separating- 8o rollers arranged between said antifrictionrollers, each separating-roller having a neck at each end and an annular groove to receive the ribs on the antifiiction-rollers, rings around the separating-rollers for engaging said necks, a cap at each end of the outer bearing member, detachably secured to said outer bearing member and means accessible from the outside of the on s, detachably securing said caps to said 00 ars. 9o 2. The combination of a central journal and a sleeve detachably mounted thereon, said sleeve and journal being provided with means for preventing relative rotation, a collar at eachend of the sleeve andengaging the 9 5 sleeve, an outer bearing member'com rising a cylindrical shell and two inner cy inders detachably secured to the shell and separated to form an annular channel, both said cylin-- ders being removable in the same direction when detached, a series ofantifriction-rollers around said sleeve each having an annular rib to engage in said channel, said sleeve being provided with an annular roove to receive and engage said annular ri s to prevent 165 I longitudinal movement of the sleeve and rollers and outer bearing member, separetingrollers arranged between said antifrictionrollers, each separating-roller having an aniular neck at each end for bearing on said collars, and an annular groove to receive the ribs on the antifriction-rollers, rings around the separating-rollers for engaging said necks, a cap at each end of the outer bearin member, detachably secured to said outer aring 1 I 5 member and means accessible from the outside of the caps detachably securing said caps to said collars. i

3. The combination with a central journal member and a sleeve member, one of said members being provided with a. pin and the other with a notch for engaging said pin for; detachably connecting and preventi relax tive rotation of said members, a co alat each end of the sleeve andengeging the sleeve, I 25 an outer bearing member com rising a-cylindrical shell and two inner cy ders detachably secured to the shell and separated to form an annular channel, a. series of antifriction-rollers around said sleeve each having 1 1':

eeeeee an annular rib to engage in said. groove, said sleeve being pro vided with an annular groove to r ceive and engage said. annular ribs to 'g'irevent relative longitudinal movement of the sleeve and rollers and outer bearing" member, sepmating-rollers arranged between said antifrictionrollers, each so aratingroller having an annular neck at eac end for hearing on said collars, and an annular TO groove to receive the ribs on the antifrictiom rollers, rings around the separatingofollers for end of the outer hearing member, detaoliably secured to sa douter bearing member and means accessible from the outside of the sens detae rably securing said caps to said CK).
